Essential Features for Choosing PCB Layout Software

December 3, 2019 , in Blog

A scientific research journal article published in 2017 reports that owning a dog typically leads to a longer life and less vulnerability to certain types of diseases for the owner. Apparently, the commonly held belief that dogs are man’s best friend has some credence. I suspect there are many benefits to having a reliable partner as we grow, age, and learn to make the journey more rewarding.

Schematic capture: An essential for PCB layout software

This is certainly true when it comes to PCB layout software. As an engineer, some of your most important decisions are what tools to use. Your choices can equip you to succeed or limit your productivity. To be a successful PCB designer requires dedication, creativity, and the right PCB layout software. Without a software program that is robust and flexible your ability to deliver for your clients is limited and so will be your project options.

There is a wide range of features to consider when it comes to PCB layout software programs and the choice of using several different tools or committing to one can seem difficult. And the choice not only impacts you but can affect the entire development team as well as the efficiency and effectiveness of the process.

All PCB layout software tools are not created equal. Therefore, before committing to a partnership, you should ensure the program has the capabilities and functionality to meet your requirements not only today but also as your designs grow in complexity. Let’s take a look at what features are essential for your design depending upon its complexity.

PCB Layout Software Essentials

In the table below, features are listed that are necessary for your design process efficiency and/or to aid your contract manufacturer in building your boards, regardless of the complexity of your design.

ESSENTIAL PCB LAYOUT SOFTWARE FEATURES

Features

Simple Design

Complex Design

Schematic CaptureStarting the design from a schematic is by far the best option, even for simple designs.For complex designs, starting with a schematic is virtually imperative. Otherwise, the board layout is likely to be replete with errors that could easily be avoided.
Automatic DRCIt is imperative that the design can be checked for rule compliance.Same as for simple design.
Forward and Backward AnnotationLaying out a board directly is much more challenging than beginning with a schematic and is a basic requirement for any design.This is even truer for complex designs.
Assisted RoutingThis is a basic requirement that any design tool should have.Routed complex boards manually without any assistance is not a task to be undertaken.
AutoroutingFor simple circuits, traces can be manually routed.For complex circuits with many vias, manual routing is extremely challenging without some automation.
AutoplacementAlthough helpful, for small numbers of components manual placement can be done fairly easily.This can be a great help for large numbers of components; however, some manual placement will undoubtedly also be necessary.
Real-time Component DataResearching a small number of components is a doable task. Thus, this capability is not really needed.For large numbers of components keeping track of their status can be extremely time-consuming. Having this data available will save significant time and avoid future component availability issues.
Export optionsAt a minimum, the program should be able to export Gerber files.The more design file package formats that the program can export widens the range of CMs that can be used to build your boards.
DFM importationFor simple circuits, it may be possible to get away with general industry standards for DFM.The more complex the design, the more critical it is for design specifications to be in alignment with CM equipment capabilities.
Signal AnalysisSimple circuits will typically have a single signal type and perhaps a power distribution network (PDN) and do not need this capability.This is advantageous for boards with multiple signals types or signals at various frequencies.
Thermal AnalysisSimple circuits will most often employ standard materials that will suffice; therefore, this capability is not required.Complex circuits typically include high power devices and multiple signal types. In these cases, the ability to ensure thermal dissipation and thermal distribution are adequate can be a great benefit.
3D VisualizationNot necessary for simple circuits, especially single or double-layer boards.Can be a tremendous benefit, especially when MCAD integration is necessary.
ECAD - MCAD IntegrationUsually, simple boards do not include enclosure integration.This capability allows for precise board dimensioning for installation.
Panelization DesignCan be performed by the CM.Aids the CM and allows you to specify the depanelization technique used.

As shown in the table above, there are essential features that your PCB layout software should possess to facilitate your design, whether simple or complex. However, as it is likely that your designs will continue to increase in complexity, it is highly recommended that you anticipate features that will become essential.
